Here's a chart comparing network ratings from the period 9/28/2009-10/11/09, which is when Anita Dunn slammed the network, and the two weeks after that ("post feud"). The numbers on the bottom right of this chart show the sequential gain for all demos (+9%( and the 25-54 year old demo (+14%).

As for competition against the cable also rans, Fox News is sweeping the top 11 cable news slots in the 25-54-year old demographic (chart below), and the top 13 slots in all demos. It's kind of ridiculous.
